Application November 1945, semi! No. 628,852

The present invention relates broadly to winches and more particularlyto improved means for anchoring one end of a cable to'the winch.

It has heretofore been the practice when fastening one end of a cable tothe winch to provide a series of holes in the flange of the winchthrough which thescable is woven or threaded back and forth. Thisthreading or weaving causes kinks in the cable resulting in frequentbreakage under strain or overload.

It is an important object of the invention, therefore, to provide meansfor anchoring one end of the cable to the winch in a manner to obviatekinking thereof with the resultant breakage when the cable is placedunder strain.

Another object of the invention is to provide cable clamping means inthe form of a pin receivable in one flange of the winch, said pin beingformed with an elongated opening adjacent one end thereof for receivingthe end of the cable, and a nut on the other end of the pin whereby whenthe pin is drawn up by the nut the cable will be securely clampedbetween the inner end of the opening and the inner face ofthe flange.

It further object of the invention is to provide a cable anchoringmember for winches wherein the elongated slot or opening is serrated orburred to aid in providing a firmer grip on the cable as the cable isdrawn tightly against the inner face of the winch flange.

A still further object of the invention is to provide a cable anchoringmember of the above character wherein the nut which is threadedlysecured on the outer end of the pin is counterbored so that the end ofsaid pin will notprotrude beyond the outer face of the nut whentightened thereby.

The above and other objects of the invention will in part be obvious andwill be hereinafter more fully pointed out.

In the drawings:

Figure l is an elevational view, partly in section, of a standard typewinch with the cable anchoring member attached to the flange thereof.

Figure 2 is an enlarged sectional view of the cable anchoring member,with the parts in the position assumed when anchoring the cable tothewinch.

Figure 3 is an elevational view in modified form of pin.

Figure 4 is a partial sectional view of a modifled form of the inventionin which a knurled weidge is used in conjunction with the pin and nuReferring to the drawing for a more detailed 2 Claims. (Cl. 242117)description thereof, a winch of standard construction is generallydesignated by the reference numeral 5 and is shown to include acylindrical shaped drum 6 on which the cable I is wound. The winch 5further includes flanges} and 9 suitably secured to each end of the drum6, said flanges being of greater diameter than the drum 6. Each flangeis counterbored as indicated at In, and as is to be understood, thecounterbored flanges 8 and 9 and drum 6 are of standard which the cableend is threaded or woven. This threading or weaving of the cable endserved to lock the cable and but has not proven satisfactory in thatkinks were formed in the cable resulting in frequent breakage whenplaced under strain or overload. In accordance with the presentinvention the end H of the cable is securely anchored to the winchwithout liability of the cable kinking and breaking. This improved cableanchoring means includes a cylindrical pin It of substantially uniformdiameter which slidably fits an opening 13 formed in the flange tadjacent the outer periphery thereof. The pin projects from the innerand outer faces of the flange, The outer end of the pin is threaded asindicated at M while the inner end is formed with an elongated openingIS. The pin is of considerable greater diameter than the cable to beclamped and the opening has a width which permits the free insertion oithe end of the cable therein. The threaded end l4 carries a nut it,which nut is counterbored as indicated at IT. The pin it and nut l6 aredesigned so that the end of the pin l2 will not protrude beyond theouter face I! of the nut l6. This is accomplished by limiting the numberof threads I on the pin and forming the counterbore I! in the nut IS.The

counterbore at the inner end of the nut l6 provides an annular abutmentface l6" which abuts against the outer face of the flange 8. Thi permitsof the threaded P rtion of the pin being disposed on the outside of theflange and provides for a firm but slidable mounting of the pin in theopening in the flange.

In the use of the device for anchoring the cable, the pin minus the nutIE will be inserted through the flange opening I I in such position thatthe elongated, opening I! will be Projected beyond the inner face I! ofthe flange 8. The end ll of the cable I is then inserted upwardlythrough the opening II to substantially the position shown in Figure 1.The nut I! is then tightened on the threads H, which action will drawthe pin l2 outwardly of the flange 8 until the cable becomes iirmlygripped between the inner face 19 of the flange and the wall 20 of theelongated opening l5. As more particularly shown in Figure 2, when thecable is firmly anchored the nut I will bear against the outer face ofthe flange 8 and be completely confined within the counterbore 10thereof. The nut I6 is confined within the flange 8 to prevent injury tothe operator of the winch or the catching of his clothes thereon. Thus,it will be seen that by the new and improved anchoring means, one'end ofthe cable II will be firmly clamped so that said cable can be wound onthe drum 8 in the normal manner. Through the use of the improved cableanchoring means, kinking or breakage is obviated.

In Figure 3 of the drawing there is shown a modified form of pin in.which the elongated opening l has one wall thereof formedv withserrations 2]. These serrations will bite into the cable when the nut isthreaded thereon in the manne previously described. In some instances,where the cableis subjected to severe strain and overload, it may bedesired to form the opening of the pin with the serrations'in order thata firmer bite of the cable can be obtained.

In the modified form of the invention shown in Figure 4, of the drawing,there is employed a tapered wedge 22, one face of which is knurled orserrated as indicated at 23. In this form of the invention the wedge 22is inserted in the elongated opening 15 simultaneously with theinsention of cable end I I, and upon tightening the nut IS, the smoothface of the wedge will engage the inner face of the flange 8, causingthe serrated area 23 to bite into and g ip cable end II;

In all forms of the invention, a cotter key 24 is provided for lockingthe nut is on the pin l2 after the cable has been securely anchored. Of

course, use of the cotter key is optional;

It is to be clearly understood that various changes in the details andconstruction and arrangement of parts may be made without departing fromthe scope of the invention as set forth in the appended claims.
